I have a Polish capper. I really like the design, size and quality. However, mine doesn't seem to work right. Since if came from Poland, I'm not going to try to return it. It doesn't want to let go of the cap. I put it on the nipple and pull to the side, lift up slowly, ....all kinds of little quirks. Still it pulls the cap back off a lot of the time. It is easier to use than the "stick" capper I have and easier to fill and "load" than the snail capper but it doesn't quite work right for some reason.
